El desarrollo de bloqueadores de moléculas coestimuladoras parece ser un campo promisorio, al igual que el de los receptores de las células tipo toll, además de los componentes genéticos que confieren susceptibilidad a la producción de citocinas tipo Th2.

Resumen
Los padecimientos alérgicos han sido un modelo de estudio para la polarización de células Th2 y es bien sabido que la síntesis de la IgE humana surge de la colaboración entre las células Th2 y las células B a través de la participación de citocinas como la IL-4 y la IL-13 y moléculas de superficie como CD40-CD40L. En la última década, algunas moléculas de superficie han sido asociadas con células Th2 humanas. Aunque estudios recientes sugieren que los receptores de quimiocinas son los marcadores más relacionados con células Th2, hasta la fecha no se encontró un marcador específico para las células Th2. Los estudios más recientes sugieren, en primer término, que las células Th1 y Th2 no son derivadas de distintos linajes celulares sino que pueden derivarse del mismo precursor Th y, bajo la influencia de factores genéticos y medioambientales, polarizarse y convertirse en células Th1, Th2 y las llamadas Th3 o reguladoras. Por otro lado, el desarrollo de bloqueadores de moléculas coestimuladoras parece ser un campo promisorio, al igual que el de los receptores de las células tipo toll, además de los componentes genéticos que confieren susceptibilidad a la producción de citocinas tipo Th2.
